Question

Help meeee!!!!!! im stuck

Answer 1

A straight line is 180, so (6x+3)+69=180
Subtract 69 from both sides and you end up with 6x+3=111 subtract 3 from both sides and you get 6x=108 divide both sides by 6 and you will end up with

X=18

Answer 2

These angles are supplementary meaning they add up to 180°

To find the value of X you must set up the equation 6x+72= 180

Subtract 72 from both sides

6x = 108

Divide both sides by six

x = 18
